# Spawning Futures
|
|
|
|
The `use_future` and `use_coroutine` hooks are useful if you want to unconditionally spawn the future. Sometimes, though, you'll want to only spawn a future in response to an event, such as a mouse click. For example, suppose you need to send a request when the user clicks a "log in" button. For this, you can use `cx.spawn`:
|
|
|
|
```rust, no_run
|
|
{{#include ../../../examples/spawn.rs:spawn}}
|
|
```
|
|
|
|
> Note: `spawn` will always spawn a _new_ future. You most likely don't want to call it on every render.
|
|
|
|
Calling `spawn` will give you a `JoinHandle` which lets you cancel or pause the future.

## Spawning Tokio Tasks
|
|
|
|
Sometimes, you might want to spawn a background task that needs multiple threads or talk to hardware that might block your app code. In these cases, we can directly spawn a Tokio task from our future. For Dioxus-Desktop, your task will be spawned onto Tokio's Multithreaded runtime:
|
|
|
|
```rust, no_run
|
|
{{#include ../../../examples/spawn.rs:tokio}}
|
|
```
